Full textCarbon dioxide (CO₂) and other pollutant emission limitations are more and more rigorous. These limits conduct cars manufacturers to study new combustion concept, in order to increase conventional gasoline engine efficiencies. Gasoline Partially premixed combustion concept (GPPC) seems to have the potential to reach these objectives, in other terms an efficiencies comparable to diesel engine by with emissions of gasoline engine, which mean a low cost after-treatment system. This study investigates, by an experimental approach, the physical process responsible on controlling this combustion concept and by the way improves it. This will be done by studying the mixture preparation and the combustion behaviour. The first part of this work concerns on determining the impact of in-cylinder thermodynamic conditions, injection strategy and the dilution rate on combustion behaviour using a single cylinder all metal engine. Three distinctive heat release rates were selected; where one represent the optimized injection phasing in term of efficiencies and pollutant emissions. The second part was dedicated to studying the process involved in GPPC combustion mode by optical diagnostic techniques on single cylinder optical access diesel engine. The impact of second injection phasing, fuel and air interaction and also the fuel combustion process allowed the validation of hypothesis emitted in the first part to explain the combustion behaviour and give ways to control this combustion mode

Full textThe Adour basin holds one of the largest populations of Atlantic salmon in southern Europe exploited by commercial and sport fisheries. Determining the relative contributions of individual rivers and hatcheries to the Adour basin populations becomes crucial to understand key sources that contribute the most to its persistence. We successfully used Sr:Ca, Ba:Ca and 87Sr:86Sr ratios as natural tags for determining the natal origins of adults from 12 tributaries. Success in discriminating between fish from different sites was greatest using Sr isotopes since the latter remained relatively constant across years at a given location. Geochemical signatures from core regions of the otolith were also used to identify fish from hatchery or naturally spawned sources. The predominance of adults spawned in the Ossau River among returning adults corresponded with long-term juvenile production trends in the Ossau River. Despite the limited upstream accessibility of the Pau River, our study demonstrated that Atlantic salmon recruits can successfully leave this river to join the adult population in the Adour basin. We observed relatively clear separation between hatchery and wild juveniles using both Sr:Cacore (wild > 2.5 and hatchery < 0.80) and 87Sr:86Srcore (wild < 0.710 and hatchery > 0.710). The return of hatchery reared fish as adult spawners represented 10% of the total sampled fish we analyzed. Almost all adults, previously identified as belonging to the Ouzom River, were hatchery produced. Adults originated from the Pau River were either wild or hatchery reared fish. We also conducted field controlled experiments that characterized the elemental uptake process in juvenile Atlantic salmon otoliths during freshwater residency. Physiological effects influenced Ba deposition. Ba:Ca otolith profiles from hatchery-reared and field collected fish were characterised by a peak at yolk absorption mark. Hatchery-reared fish stocked in a river also displayed a peak of Ba:Ca following transfer which was not related to the water chemistry. Our experiment revealed a 20-day lag time between initial Ba:Cawater changes and Ba:Caotolith saturation. Results suggested that such effects should be considered during any attempts to determine rivers of origin of Atlantic salmon based on otolith elemental composition or reconstruct the movement of individual fish among and within streams

Full textPartikelsuspensioner förekommer i många sammanhang i naturen och industrin. I denna masteruppsats studeras rörelsen hos en enstaka stel sfäroidisk partikel i Stokesflöde numeriskt med hjälp av en randintegralmetod och en ny specialiserad kvadraturmetod som kallas quadrature by expansion (QBX). Metoden fungerar för masslösa eller tröga sfäroider, som kan placeras i ett godtyckligt underliggande Stokesflöde. En parameterstudie av QBX-metoden presenteras, tillsammans med valideringsfall för sfäroider i linjärt skjuvflöde och kvadratiskt flöde. QBX-metoden kan beräkna kraften och momentet på sfäroiden samt den resulterande stelkroppsrörelsen med små fel på kort tid, typiskt mindre än en sekund per tidssteg på en vanlig persondator. Nya resultat presenteras för rörelsen hos en trög sfäroid i kvadratiskt flöde, där skjuvningen till skillnad från linjärt skjuvflöde inte är konstant. Det visar sig att partikeltröghet medför en drift i sidled mot områden i fluiden med högre skjuvning.

With the advance of the nano technology, nowadays there are more and more materials and devices which are relevant to nano dimension. This study deals with electric double layer (EDL) potential at solid/electrolyte interface within nano dimension. The measurement of EDL potential is typically achieved by using the atomic force microscope (AFM), the mathematical model of surface force, and the Matlab software. The surface force was regard as sum of Van der waals force and electrostastic force by setting up low probe velocity. In addition the surface of sample was modified by chemical mechanical polishing (CMP) process. The simulation results of Comsol software with Poisson Boltzmann、Modified Poisson Boltzmann equations show that this methodology is valid. These surface force experiments found that the thickness of stern layer could be 0.68 to 0.78 nanometer. The zeta potential are -33, -10, millivolt respectively in NaCl and MgCl2 electrolyte with Au surface, and the zeta potential are 23, 8 milivolt respectively in NaCl and MgCl2 electrolyte with glass wafer. In the end, according to lately literatures, the range of zeta potential is from -32 to -67 milivolt with Au surface, and the zeta potential in this study is -33 milivolt. It shows that under these conditions, like good surface roughness, well probe setting, the electric double layer potential at solid/electrolyte interface within nano dimension can measured by AFM device and mathematical software.

Part Ⅰ Ionizable groups in polyelectrolyte gel interact electrostatically with ions in surrounding electrical potential. This work studies the swelling kinetics via water uptake by dry samples and zeta potentials by streaming potential measurement of Poly (vinyl alcohol-g-sodium styrenesulfonate) (PVA-g-SSS) and Poly (acrylonitrile- acrylamide-acrylic acid) (P(AN-AAm-AA)) gels in aqueous KCl solutions. The water absorption increase and then decreases with the concentration of KCl, and the diffusion coefficient of water into dry gels is maximal at the minimum water uptake. The maximum ion shielding on the gel surface occurs to the situation with lowest water uptake at intermediate electrolyte concentrations, and then excess K+ ions enters the swollen network, subsquently being hydrated at the higher electrolyte concentrations. Moreover, the water swelling deviates more significantly from the Fickian mode with the higher electrolyte concentrations, due to hysteresis on the swelling-driven mechanical relaxation caused by the K+. Both gels, have negative zeta potentials, whose absolute value increase with KCl concentration and becomes zero at intermediate KCl concentrations. Such a point-of-zero-charge phenomenon is also a manifestation of ion shielding on the gel at interface. Part Ⅱ The contact angle of air and n-octane on P(AN-AAm-AA) and P(VA-g-SSS) hydrogels in aqueous KCl solutions at 25℃ were measured. The interfacial energy between gels and water decreases with the decreasing water content of gels. The water content of gels decreases and then increases with the concentration of surrounding KCl solutions, and the minimum point implies the maximum shielding on the gel surface, maximum water-gel interaction energy at interface, and minimum interfacial energy. The relations between zeta potential of gel interface and interfacial energy of gels leads to the conclusions that the surface charge density of gels decreases with the ion content of gel bulk, and the capacity of electrical double layer is non-zero. The valence data of mobile ions in diffuse layer indicate that the permeability of gel interface make the electrical behavior of gel-ion interface different from the rigid interface.
